METHOD' OF MAKING BATS.

Application'mea August 16, 1927. serial 1ro/213,368.

The invention has for its object to provide a new and improved method of making bats for use in upholstering automobile and Pullman car seats and the like by the employment of which method the bats may be much more economically produced than has heretofore'been possible and are of a better quality for their intended purposes thanconventional forms of batsnow in use.

In its more detailed nature the invention resides in the provision of anew and improved method of making bats of thel folded or unfoldedv type and comprehends the steps of forming a continuous wide bat stock sheet of a plurality of laps of like materials or combinationsy of materials, layingtensile strength giving strips between certain laps of the stock sheet in spaced relation, slitting the wide sheet between the strips to provide -a series of individual bat units, di-

. viding the sheet transversely at intervals to provide bat lengths serially arranged, folding'the bat yunits when folded type bats are being formed, and winding the bats in individual spirals, j

Other objects will in. part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, vcombination and arrangement of parts, all of which will be irst fully described in the following detailed description, Vthen be particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which j 'l Figure l is a diagrammatic side elevation illustrating the method.

In the drawing in which I have diagrammatically illustrated the steps of my method,

1 indicates a series of travelling aprons or` tables preferably arranged horizontally to feed the material along, vit Vbeing understood that any suitable means' for so conveying the material may be employed. In the drawing four such aprons are shown and will be referred to in detailas first, second, third and-fourth aprons. l

The numeral 2 indicates any suitable lap laying meansA` as for example two rolls of lap or batting sheet material from which individual laps 3 and 4 areilaid uponthe first apron in superimposed relation one upon the other4 to form a bat stock body portion 5.

As it leaves the apron the body 5 passes through feed and presser rolls 6 which exert just enough pressure on the said body to interlock the fibres of the'laps 3 `and 4 without matting or appreciably compressing' the said bat body port-ions. f

The bat body portion 5 next passes over anysuitable carry-over conveyor such as the camel-back apron 7 diagrammatically pil- Vlustrated in' the drawing.

Lap laying means 8 similar to the lap laying means Zhereinbefore referred to may be employed to lay individual superimposed laps 9 and 10 upon the secondapron l to form a bat body portion ll similar in construction to the body portion 5 hereinbefore referred to. After being formed the body portion 1'1 passes through feed and presser rolls 12 which maybe similar in construction and function to those 6 here- `inbefore referred to in detail, and from the said rolls the said bodyv portion passes upon and over the third apron, at `r adjacent theV end of which the bat body portion 5 is deposit-ed thereupon so that the said portions 5 and 11 collectively form the bat stock body proper or the completed bat body 18. In this manner a bat stock body 13 is formed which is relatively wide and continuous in length.

Just before the bat bodyportions 5 and 11 are laid one upon the other to form the bat stock body 13 a plurality of tensiley strength providing strips 14 are laid between vthe said portions5 and 11 in equi-distantly spaced relation. The said strips are of continuous length and may be formed of ordinary paper, gummed paper, fabric, glazed Wadding or soft rolled cotton rope. Y

The laps 3 4 and 9-10 may all be formed of cotton of the same grade or they may be arranged in combinations of different grades of cotton or of cotton and curled hair. See Figures 6 and 7 for examples. Thus inferior grades of cotton may be used toward the center of the inished bats and better grades of cotton at the outside, or the centers of the bats may be formed of cotton and the outer portions of curled hair as illustrated in the said figures. Thus by employing the method disclosed for forming the bat body proper of individual laps it is possible to form the bat stock to suit the requirements of particular orders being filled.

The bat stock sheet proper 13 after being formed is passed through the sets of presser and feed rolls 15 and is longitudinally slit as at 16 to form a plurality or series of narrow strips forming individual bats 0r bat units 17.

In the process of forming the completed bats the stock sheet is cross-cut or divided at regular intervals as at 18. This cross cutting operation may be accomplished in the manner illustrated in Figure 3 of the drawing by a cross knife which descends upon a notched abutment .rod so that the bats will not be completely severed but will be weakened so that a user of the bat can easily and conveniently sever them at will, or the said cross-cutting operation may be 'accomplished in the manner indicated in Figure 4 of the drawing. In this figure the bat body portions 5 and 11 are completely severed by suitably spaced and timed knives 19. Theknives 19 are so spaced and timed in operation that after the operation has been started the cuts made by the knives will be arranged at like points .in the finished bat as illustrated in Figure 5 of the drawing so that except for the tensile strength providing strips 14 the bats will becompletely severed at regularintervals. Thus the bats are divided into predetermined regular lengths and thesaid lengths are\held together only by the tensile strength providing strips which may be readily severed when it is desired to use the bats.

When it is desired-to form bats vof the folded type the longitudinal slicing means 16 are less in number so that the bat units are fewer andwider as -illustrated in Figure 8 of the drawing. After being slitformed the bat units are suitably folded as at 20 toy'form the desired finished bats.

On leaving the fourth or final apron 1 the finished bats form slack loops 21 and pass to any suitable winding means 22 to be Wound into individual spirals or coils for convenient shipment and use.

In the drawing in Figures 6 and 7 curled hair laps are indicated at 23 and the ordinary cotton laps at 24, the paper or other tensile strength providing strip being indicated at 25.

In the foregoing description I have disclosed an economical and convenient method of forming a wide continuous sheet of batting stock having tensile strength providing strips therein, dividing the said sheet longitudinally to provide a plurality or series of individual bat units, cross-cutting said parts or units to provide weakened or bat length defining* portions, folding the bat units (when the folded type of bats are being formed) and Winding the finished bats in individual spirals or coils for shipment and use. The herein disclosed method is such that bats ofcomposite materials may be formed much more conveniently and economieally than has hereinbefore been possible, Which are more easily adaptable for their intended purpose, and which may be manufactured at a great saving inlproducy tion costs than is possible in bats now commonly used.

It 'is to be understood that this method may be carried on either by hand or by the emplo ment 7o'f an suitable machinery. capab e of accomplis ing the steps and results herein described, and while I have disclosed a 'machine capable of accomplishing the purposes referred to herein in my co-pending application, Serial No. 224,496 filed Oct. 6, 1927, the herein disclosed method may be carried on by the use of any other machinery designed' for `accomplishing the necessary steps.

From theforegoing description, taken yin Connection with the accompanying drawing, itis'thought that the manner of carrying out my improved bat forming method and the advantages of the bat constructed in accordance with the method will be readily apparent to those skilled in the art to which it relates. g
